Amphiphyte
Amphiphyten or amphibious plants , also litorale helophytes (shore plants) are plants that an intermediate position between hydro- occupy and helophytes. They are plants that can live as aquatic plants when the water level is high and as land plants without water .
A distinction is made between facultative amphiphytes; They live mainly in zones with strongly fluctuating water levels, their photosynthesis is restricted submerged. The obligatory amphiphytes are largely without a milieu focus. They form both aquatic and terrestrial forms and can assimilate permanently under water without any loss of performance.
Example for amphiphytes:
- Water knotweed ( Polygonum amphibium )
- Common fir frond ( Hippuris vulgaris )
Example for vegetation classes of amphiphytes:
- Littorelletea uniflorae (Strandling Society)
- Isoeto-Nanojuncetea bufonii (dwarf rush society)
